Gray Cast Iron

The procurement process FAG organization is critical to the final quality of his product in terms of effectiveness and efficiency.
The organization to ensure that specified requirements are met and agreed upon during all phases of gray iron castings, ductile and bound, has developed a set of documents that define and describe the operational arrangements of the phases / sub-phases of construction Mergers and follows very closely the services that run with external partners as heat treatment and painting.
